Custombuild Exim is installed over Debian version

[rvandam]

I have some small issues with Exim (see http://forum.directadmin.com/showthread.php?t=54929 )

It turns out that Exim was already installed on my system and I didn't see it before install (I checked Apache etc. but oversaw Exim) The mail system is running fine now, but I fear things go wrong when Apt updates Exim. And I also want to resolve the minor issues.

The custombuild version is also installed over the Apt version.

apt list --installed |grep exim
exim/now 4.86-1 amd64 [installed,local]

exim -bV
Exim version 4.89 #2 built 24-May-2017 08:22:37

What happens if I remove Exim by Apt, and re-install Exim by Custombuild?

Is there another way to manually remove Exim from the Apt package manager? I saw something like remove the exim entries in /var/lib/dpkg/info

Edit:
I set Exim on hold with: apt-mark hold exim
This will prevent an update and overwrite of the custombuild version.

Does a normal directadmin install have an Exim entry in /etc/cron.daily ?

Hello,

As far as I know installation script of Directadmin installs Exim from *.deb package on Debian and *.rpm package on CentOS. So it might be that you have one installed by Directadmin itself.

Removing Exim by apt and re-installing it with Custombuild should be safe, make sure first you've got users' backup before you precede with it on your server.

Ok I removed exim by Apt, en reinstalled by custombuild. This resulted in a failing mailsystem (all incoming mails refused with a user unknown error, and no mails going out). Turned out the file /etc/system_filter.exim was missing.

Everything seems to work normally now. I did a wget -O /etc/system_filter.exim "http://files.directadmin.com/services/system_filter.exim"
